Interesting matchup here that is great to see as two different M engine philosophies battle it out. The M5 is the camera car but unfortunately a cell phone camera is used by the M5. Still, the video is clear so you can see exactly what happens. The modifications on the M5 are a Stage 2 tune that is not named, downpipes, and a custom straight piped exhaust. The E92 M3 is supercharged with the Active Autowerke Gen 2 Level III supercharger system.

So, um, yes, you can say the new F80 M3 and F82 M4 respond pretty well to bolt on modifications. Journalists are still getting their hands on stock cars to test but Burger Tuning (BMS) already has the car over 500 wheel horsepower. This is not too surprising as with a mild bump in boost on a beta Stage I BMS tune the car already showed 479 horsepower at the wheels. Now with some further refinement to the tune and some ethanol (E85) the result is over 500 whp.

Here is a street race for some money between an X71 X6M and an E60 M5. The race is for money although only a $1000 which is hardly enough to even cover the modifications on the cars. The two cars race on a city street with people behind them shutting down the traffic so obviously do not try this at home. The race is from a stop and so in theory should favor the X6M with its all wheel drive against the rear wheel drive E60 M5 on street tires.

The BMW F82 M4 is a very hot car right now. It is winning comparison tests against vaunted German competition such as the Porsche 911 and the Audi RS5. The car is delivering much more performance than its specifications would lead you to believe and overall is drawing praise from the automotive world. Vorsteiner grabbed an Austin Yellow M4 and gave it a set of their VSE-003 forged monoblock wheels reminding us the M4 has beauty to go with that brawn.

BMW officially released the 2015 F36 4-Series Gran Coupe earlier this year. This of course led to speculation (some sites reported it as confirmed) as to whether BMW would produce an M variant using the F36 chassis. An M4 Gran Coupe would obviously somewhat overlap with the F80 M3 but the same could be said for overlap between the M6 Gran Coupe and the BMW F10 M5. The market already proved that there is room for four door sedans and four door 'coupes' as the Mercedes E-Class and CLS-Class demonstrate.

A recent article on a quick Auto Express video comparison between the M4 and RS5 got a lot of attention partially due to just how much stronger of a performer the new M4 is over the Audi RS5. The performance comparison between the two cars is pretty one sided. Here we have much more data than the quick Auto Express video thanks to the German publication Autozeitung and although it is in German numbers are universal.

Porsche 911 and BMW M3/M4 comparisons are nothing new. The M3 traditionally offered Porsche 911 level performance but at a lower price point of entry with greater daily usability. The Porsche 911 of course offered the Porsche prestige and the driving dynamics of a lighter two seat sports car. Not much has changed although the M car now offers much more brute force than the 911. The power, torque, and performance gap is the greatest it has ever been.

Some hot supercharged M3 on M3 action here! This video is courtesy of a BimmerBoost member who attended a recent roll on race event in Chicago. His car is the camera car here and it is an E92 M3 with a 6-speed manual and the Gintani Stage II supercharger system. The silver E92 M3 also is a 6-speed manual car but it is equipped with the Evolve E600 supercharger kit. The Evolve car is running pump gas and less boost.

Active Autowerke recently introduced their Prima non-intercooled E46 M3 supercharger kit. This kit uses the well known Rotrex C38-92 spec blower to great results. Starting at $5995 (TTFS has it on sale for $5500) the kit is a very good value and at just 5.8 psi of boost on an otherwise stock E46 M3 puts down 426 horsepower to the wheels and 297 lb-ft of torque at the wheels on pump gas and the stock fuel system. Now Active Autowerke is also introducing a Prima Plus kit for those that want more.

As an automotive enthusiast who participated in a few different discussion forums over the years experience has shown that putting performance in context with Audi fans is frustrating. Why? Well, let's take this example of the Audi RS5. It's an absolutely beautiful car with a gem of a 4.2 liter naturally aspirated V8 motor revving to 8500 rpm and sending 450 horsepower to all four wheels. Your average car fan will see the 450 horsepower figure and think it beats the BMW M4 with 'only' a 425 horsepower rating.

The upcoming F87 BMW M2 will be a very popular vehicle. It has been a while since BMW had a lightweight, affordable, well balanced, and fun to drive car where electronics and heavy luxury features did not take away from the driving experience. The M2 proposes to get back to some of the Ultimate Driving Machine principles and due to its price point of entry it will be far more attainable for far more BMW enthusiasts.

Congratulations to Gintani who increased their own S85 V10 horsepower record from 710 horsepower at the wheels to 774 horsepower at the wheels. This was done with a Vortech T-Trim supercharger and boost around 10 psi along with 100% methanol injection plus MS109 fuel. It is also interesting to see how the Vortech Ti-Trim supercharger compares to the Vortech Si-Trim on the same S85 V10 engine.
